She is the alter ego of teenager Mary Batson (adopted name Mary Bromfield), twin sister of Captain Marvel's alter-ego, Billy Batson. Like her brother, Mary has been granted the power of the wizard Shazam, and has but to speak the wizard's name to be transformed into the superpowered Mary Marvel. Mary Marvel was one of the first female spin-offs of a major male superhero, and predates the introduction of Superman's female cousin Supergirl (also created by Otto Binder) by more than a decade.

Following DC's licensing of the Marvel Family characters in 1972, Mary Marvel began appearing in DC Comics, co-starring in DC series such as Shazam! (1973-1978) and The Power of Shazam! (1995-1999). Two limited series from 2007-2009, Countdown and Final Crisis, feature an evil version of Mary Marvel (commonly referred to as Black Mary Marvel[citation needed]), having acquired powers from first Shazam Family archenemy Black Adam and further from super-villain Desaad and the technology on the distant planet Apokolips. In current continuity following DC's 2011 New 52 reboot, Mary Bromfield appears as one of Billy Batson's foster siblings, and can share Billy's power at his whim to become an adult superhero similar to the traditional Mary Marvel (the "Marvel" monikers having been retired with the reboot).

Mary Marvel was introduced into Fawcett Comics' Marvel Family franchise a year after a young male counterpart, Captain Marvel Jr., made his debut. Artist Marc Swayze based Mary Marvel's design and personality upon American actress Judy Garland.[1] Mary was introduced in Captain Marvel Adventures #18 as Mary Bromfield, a girl who discovers she is the long lost sister of Captain Marvel's alter ego Billy Batson.

Soon after her introduction, Mary Marvel headlined Wow Comics, and by 1945 had her own Mary Marvel book. She also appeared in The Marvel Family book with Captain Marvel and Captain Marvel Jr. In her solo adventures, Mary soon gained sidekicks in her kindly Uncle Marvel, who was not actually her uncle nor a Marvel, and his similarly nonpowered niece, Freckles Marvel. Uncle Marvel was eventually made the Marvel Family’s manager, and also served as Mary’s guardian.

Just before the Marvel Family's adventures ceased publication in 1953, Mary Marvel’s costume and appearance were altered: the neckline of her blouse was lowered slightly, her hair was shortened, and she now wore yellow slippers instead of the customary Marvel Family yellow boots. After Fawcett canceled their superhero comics line because of a copyright infringement lawsuit with National Comics (later DC Comics), Mary Marvel and her teammates went unseen for years.

In 1972, DC Comics licensed the rights to the Marvels, and revived them in a new comic series called Shazam!. Mary, Cap, and Junior appeared in both new stories and reprints of their classic stories. According to Shazam #1 the Sivanas had put the Marvel family into suspended animation for 20 years, along with themselves (by mistake) and much of the supporting cast. The comic book was canceled by 1978, and the Shazam! stories were relegated to the back pages of World's Finest Comics (from 1979 to 1982) and Adventure Comics (from 1982 to 1983). After the 1985 Crisis on Infinite Earths miniseries, Captain Marvel’s origin was rebooted in the Shazam: The New Beginning miniseries in 1987. The Marvel Family was written out of the Shazam! mythos, and neither Mary Batson nor Mary Marvel appeared in DC Comics for several years.

Mary Batson was reintroduced in The Power of Shazam! graphic novel by Jerry Ordway in 1994. An ongoing series followed in the next year, and Mary Marvel was introduced into the modern DC Universe with a new origin story in Power of Shazam! #4.

When calling upon her powers, Mary is transformed into an adult resembling her late mother (in the same way that Billy resembles his father when in Marvel form). Mary shares the title of Captain Marvel with her brother. Various characters in the series distinguish the two by gender when addressing them, addressing Mary as "the lady Captain Marvel".

At first, Mary’s costume was the same as her original one. However, beginning with Power of Shazam! #28, Mary donned a white costume to distinguish herself from her brother. The color change was retained for most future uses of the character during the next decade.

After the Power of Shazam! series ended in 1999, Mary’s superpowered alter ego was officially rechristened "Mary Marvel." In 2002 she had lunch with Supergirl in "The Clubhouse of Solitude", in the spoof graphic anthology "Bizarro Comics". Since then, she has guest-starred in both Superman and Supergirl comics. In 2003, Mary became a member of an offshoot of the Justice League known as the Super Buddies in the Formerly Known as the Justice League miniseries, which juxtaposed her Golden Age-era personality with the modern-day world for comic effect.

Mary Marvel appears briefly in several stories relating to DC's 2005-2006 Infinite Crisis crossover. Mary also appeared in DC's weekly limited series 52, with her most substantial appearance being in 52 #16 as the maid of honor at the wedding of Black Adam and Isis, two Shazam!-related characters. She was defeated by Black Adam during World War III (DC Comics) along with the other Marvels.

In 2006, DC began a revamp of the Shazam! mythos with Judd Winick and Howard Porter's Trials of Shazam! limited series. The series began with a preview within the pages of Brave New World #1 in June 2006, in which Mary Batson loses her powers, suffers a three mile fall, and falls into a coma. This set up Mary's appearances as a main character in Countdown, a weekly DC series which served as the successor to 52. During the course of the series, head writer Paul Dini and his collaborators had Mary acquire the powers of Black Adam, which give her a new look including a form-fitting long-sleeved black uniform and skirt with black lace-up boots. While the series tracked the character's struggle between good and evil, due to manipulation by supervillainesses Eclipso and Granny Goodness (promotional material for the series used the catchphrase "Seduction of the Innocent," a reference to Fredric Wertham's book of the same title),[citation needed] Mary emerged from the series under the influence of Superman villain Darkseid.

This darker Mary Marvel appears in DC's 2008 crossover series Final Crisis, written by Grant Morrison and illustrated by J. G. Jones, as a Female Fury, with another design change (to match the styles of the other Furies) and a fully evil personality due to possession by the New GodDesaad.[2] Though defeated by Freddy Freeman/Shazam before end of the Final Crisis miniseries, the evil Mary appeared again in the "Black Adam and Isis" arc featured in Justice Society of America (vol. 3) #23–25, by the end of which she has lost her powers and returned to being a normal teenage girl.

In 2011, following its Flashpoint company-wide event, DC cancelled made sweeping continuity changes to some comic book series and minor ones to others, as part of its relaunch event "The New 52". Captain Marvel, now known as Shazam, received a new origin story as part of the backup feature in the relaunched Justice League. Mary does not feature in the new continuity until Justice League #8 (2012), and is not transformed into a Marvel for the first time until Justice League #21 (2013), when Billy directs his powers into her, Freddy and three other foster siblings during a fray with Black Adam.

As infants, twins Billy and Mary Batson were nursed by a woman named Sarah Primm. When the Batsons' parents die in a car accident, Primm was required to send both children to an orphanage. However, Primm is determined to at least give one of the children a home, and arranges for Mary to secretly take the place of another baby girl who had suddenly died while under Primm's care. As a result, Billy is sent to an orphanage while his sister is raised by the wealthy Mrs. Bromfield.

Several years later, Billy Batson becomes a teenage radio announcer. While hosting an on-air quizbowl, he receives an urgent letter from Sarah Primm, now on her death bed, requesting his presence. Billy goes to see her during a break, and Primm tells him the secret of his long-lost sister. To help him find Mary, Primm gives Billy a locket broken in half and tells the boy with her last breaths that Mary wears the other half.

After the quizbowl broadcast is over, Billy tells his best friend Freddy Freeman about his sister and the locket. Billy then recalls that one of the quizbowl contestants, a rich girl named Mary Bromfield, wore a broken locket. He and Freddy trail Mary’s limousine in their superpowered forms of Captain Marvel and Captain Marvel Jr. and find themselves called into service to save Mary from a gang of kidnappers.

Captain Marvel then learns that Mary's locket matches his own, and that she is indeed Billy’s sister. The Marvels reveal their secret identities to Mary, who wonders if, since she is Billy’s twin, she could become a Marvel by saying the magic word "Shazam". Billy, however, is assured that “Old Shaz—er—you know who—wouldn’t give his powers to a girl!”

Just then, the kidnappers awaken then bind and gag Billy and Freddy, preventing them from saying their magic words. Mary realizes that Billy cannot say Shazam, inadvertently saying the word. She is then struck by a magic lightning bolt and transformed into a super-powered version of herself, later christened "Mary Marvel" by her brother. She then defeats the thugs by herself, realizing that she is invulnerable to bullets when they fire at her and has super strength, and frees Billy and Freddy. Shazam then reveals the 'goddesses' she gets her powers from.

Mary Marvel's updated DC origin was presented within the pages of the Power of Shazam! graphic novel and ongoing series, written by Jerry Ordway.

Prominent archaeologists C.C. and Marilyn Batson are assigned by the Sivana expedition on an excursion to Egypt. They take along their young daughter Mary, but are forced to leave their son Billy in America with C.C.'s half-brother. The elder Batsons are killed by their associate Theo Adam, who then kidnaps Mary. Upon Theo Adam's return to the United States, Adam’s sister, a maid named Sarah Primm, takes Mary into her care. Primm arranges for her childless employers, Nick and Nora Bromfield, to illegally adopt Mary. As Mary Bromfield, the young girl grows up living an idyllic life in a wealthy family, but continuously has dreams of another family with a brother she has never seen.

Meanwhile, Billy eventually finding himself on the streets, and is given the power to become Captain Marvel. He learns that Mary is still alive, but after four years of searching, neither he nor his benefactor, the wizard Shazam, can find the girl. The only thing Billy has to remember Mary by is her favorite toy, a "Tawky Tawny" doll, which was shipped to America with the Batsons’ possessions after their murders.

As a young teenager, Mary enters a regional spelling bee held in Fawcett City and emceed by Billy, who works as an on-air reporter for WHIZ radio. After saving Mary from kidnappers twice as Captain Marvel, Billy notices how much Mary Bromfield reminds him of Mary Batson and has an undercover cop named “Muscles” McGinnis retrieve the girl’s forged adoption record. Learning that Mary is indeed his sister, Billy tries to figure out a way to let Mary know he is her brother. The old "Tawky Tawny" doll suddenly transforms into a full-sized humanoid tiger and comes to life, instructing Billy to take it to Mary. As Captain Marvel, Billy flies out to the Bromfields’ hometown of Fairfield to deliver the doll and the adoption papers to Mary.

Captain Marvel arrives at the Bromfield estate and changes back to Billy Batson to deliver the package, but is immediately kidnapped by the thugs who helped Primm forge Mary’s adoption records. Mary, not having seen Billy, takes the package and opens it, discovering the adoption records and the Tawky Tawny doll. Once again, the doll comes to life and instructs the bewildered girl to say the magic word "Shazam" and save her brother. Mary complies and is transformed by a bolt of magic lightning into a superpowered doppelganger of her deceased mother. She saves Billy, who transforms into Captain Marvel to help Mary defeat the thugs, but the two Marvels cannot save Sarah Primm, who is murdered by one of the thugs.

In the eleven page preview to Judd Winick and Howard Porter's Trials of Shazam! limited series appearing in DC's Brave New World one-shot comic (June 2006), Mary Marvel loses her powers in mid-flight as an after-effect of the death of the wizard Shazam by the Spectre in Day of Vengeance #6, and falls from a height of three miles (this contradicts her appearances in the 52 series, as she appears in that series using her powers, despite 52 taking place chronologically after Day of Vengeance). Mary survives the fall but goes into a coma, and Freddy Freeman, who lost the power to become Captain Marvel Jr. in the same way, has her transported to a hospital in New York City where he can keep watch over her. He spends all his money to help her.

In Countdown #51, Mary is released from the hospital. She finds that she is still powerless and a note left by Freddy Freeman with a nurse asks her not to look for him as he is trying to get the powers of Shazam back, per the orders of Marvel. Making her way to Gotham City (despite being warned by Madame Xanadu to avoid the place in Countdown #50),[3] Mary stumbles upon the former Kahndaqi embassy while being chased by violent criminals from the subway, who are killed by Black Adam. Black Adam angrily threatens her. Mary tells Adam how much she valued her powers and how she desires to regain them. Adam, bitter over the loss of his wife Isis and brother-in-law Osiris during the events of 52 as well as his failure to resurrect the former, gives Mary his powers instead of killing her. He is transformed into the mortal Teth-Adam, whom Mary rescues from a wall toppling on him. Mary wears a black form-fitting costume and wields Adam's powers as a darker, angrier character.[4] While searching for a tutor to help her harness her power at the reformed Riddler's advice, she encounters Klarion the Witch boy in a market for dark magic, who tries to take her power, then Zatanna, who banishes her from her home after a fight, and then Eclipso, who only fuels her wild abandon. She uses a rougher justice, such as turning soldiers to stone and shrinking poachers so their quarries chase them.

Their alliance, however, seems to break down when Eclipso, hoping to please her master Darkseid, offers the young and pretty Mary as his new concubine, reasoning that the two women could always leech Darkseid's arcane knowledge, slay him, and take his place. Mary refuses to sell herself for more power, beats Eclipso with her own crystal, and flees, enraged. Eclipso catches up to her and regains the diamond. Eclipso then departs, leaving Mary alone again. Some time later, Eclipso returns hoping to finish her off, but Mary is too strong for her.

Mary experiences a change of mind, and upon realizing that Black Adam's powers are as responsible for her corruption as Eclipso, divests herself of them by feeding the lightning bolt into Eclipso, who tries to kill her and take her power. Both women lose their powers and fall into the ocean. However, an unpowered Mary lands on Themysciran soil, where Queen Hippolyta drafts her in the rebellion against Granny Goodness, who is posing as the goddess Athena.

Mary, Holly Robinson, and Harleen Quinzel manage to reveal Goodness' deception, and the trio follow her to Apokolips. After escaping the Female Furies, Mary starts to hear the voices of the gods. The group manages to free the Olympian gods from an Apokoliptan chamber, and Mary Marvel's powers are restored along with her white costume, which now has a gray lightning bolt and long sleeves.

After journeying with the Challengers to Earth-51 and witnessing the Great Disaster occurring there, Mary finally returns home to find Darkseid waiting for her. Reminding her of how strong she felt using Black Adam's powers, and claiming the gods do not trust her as much now, he returns them to her, restoring her black costume. She then confronts Donna Troy, Kyle Rayner, Forager, and Jimmy Olsen, seizing Jimmy to take him back to Darkseid. When Donna questions Mary's use of the powers, Mary insists that she is not evil, merely "driven".[5] After Darkseid's defeat, Mary returns to Black Adam, asking to be a part of a new Black Marvel Family. Adam refuses her and, after a big tantrum, she decides to become a solo superheroine.

Mary returns in Final Crisis, still apparently in Darkseid's thrall, wearing a new black costume with more of a punk look. She attacks Wonder Woman, scratching the Amazon's upper arm and infecting her with an unknown virus delivered from a broken glass vial bearing a gold Omega symbol. Later, when the heroes of Earth attack Blüdhaven, Black Adam notes that she's been possessed by one of the New Gods, a "leering old man". The possessed Mary claims to have a new dirty magic word, a blasphemous name of power, and to have new gods. During a heated battle with Supergirl, Black Adam learns that the evil god Desaad was the one who possessed Mary. Black Adam tries to kill her but is stopped by Freddy. Later, distracted by hordes of Anti-Life followers about to attack, Freddy Freeman, the new Captain Marvel, grabs Mary and uses the last of his magic to transform them back to normal. Though horrified by her actions while possessed by Desaad, and saying that she never meant for this to happen while crying, she is seen standing with Freddy with clubs in their hands, awaiting the end of the world.

After the end of the Crisis, Mary is recruited by Black Adam and Isis, who have taken over the Rock of Eternity formerly lorded over by the wizard Shazam by defeating Captain Marvel and stealing his powers, using the magic scarab Shazam used to take Black Adam's powers. During a battle between Black Adam, Isis, and the Justice Society, who had been summoned by Billy, the evil Mary Marvel abducts a powerless Billy Batson and forces him to become a teenage Black Marvel by sharing her powers and forcing him to say "Mary Marvel".[6]

The two now evil Black Marvels join Adam and Isis, who are intent on using the power of Shazam to destroy the modern world, in fighting the Justice Society. When Isis begins attacking the citizens of Adam's native Khandaq and Adam's friend Atom Smasher, he switches loyalties and joins the Justice Society's Flash and the spirit of Mary and Billy's father in helping resurrect the wizard Shazam from the Rock of Finality, where he has been sealed in stone. Black Adam gives up his powers to restore the wizard to life. Shazam promptly and angrily takes his powers back from Mary, Billy, and Isis, turns Teth Adam and Isis to stone, and closes off all contact to the Rock of Eternity to the Batson kids upon stating that Billy and Mary failed him. He also threatens to go after Freddy for stealing his name. The two Batsons are later seen wandering the streets of Fawcett City, homeless, and wondering what happened to their father's spirit.[7]

Mary and Billy are briefly seen during the events of Blackest Night, now living in an apartment in Fawcett City. While watching news reports of the various heroes and villains being reanimated as Black Lanterns on their laptop, Mary remarks how scary it is to not have her powers anymore.[8]

Mary is approached by Blaze, who offers to restore her and Billy's powers in exchange for her killing Freddy. Mary seems to go along with the deal, appearing to poison Freddy. However, when Blaze arrives to claim Freddy's powers, he gets up and attacks her. With a little help from Mary and Billy, Freddy defeats Blaze and sends her back to hell, later promising them that he will find a way to restore their lost powers.[9]

In The New 52 (a reboot of the DC Comics universe), Mary appears as Mary Bromfield. She first appeared in Justice League #8 as part of Billy's new foster family along Mr. and Mrs. Vasquez, Pedro Pena, Eugene Choi, and Darla Dudley. She is the oldest member and possibly the den mother.[10]

As Billy's twin, Mary shared Billy's ability to transform into a superhero by speaking the name of the wizard Shazam. In her petite superpowered state, Mary Marvel originally wore a red short-sleeved blouse and red skirt lined with gold trim, which included a lightning bolt insignia and cape.

The Fawcett and pre-1985 version of Mary Marvel did not derive her “Shazam” powers from the male mythological figures who empower Billy, but from a set of female benefactors: Selena for grace, Hippolyta* for strength, Ariadne( later changed to Artemis, Greek Goddess of the hunt) for skill, Zephyrus for fleetness (and flight), Aurora, (later changed to Greek Goddess Aphrodite) for beauty, and Minerva for wisdom.

Although these deities were originally described and depicted as goddesses, Zephyrus is actually a male god. In addition, the list does not account for all of the superhuman traits shared by Billy and Mary, specifically Captain Marvel's powers of invulnerability, stamina, and courage. The original Mary Marvel remained a teenager when she transformed rather than becoming a mature adult like Billy. Pre-Crisis, it is revealed she cannot call on her power for 24 hours every 1,000 years, as Shazam loses his powers during that time (although he is still able to send his spirit to contact her), and therefore so must she. In one story she is able to call on the goddesses to send an even greater lightning blast to blast away earrings that are drawing her lightning away.(Mary Marvel Comics 1) Pre-Crisis if the Elders who power her are incapitated she cannot call down the magic lightning to transform. It is shown a recording of her voice can transform her, once Georgia Sivana took advantage of this with a jukebox, turning Mary back, knocking her out with a cosh, then binding her to a chair and gagging her. However, Mary knocked the jukebox over setting it off, then for the first time with her mouth gagged Mary's voice summons the lightining. She then destroys the jukebox. In one story it is claimed Mary is weaker on Earth-1 than Earth-S.[11]

A version of Mary Marvel, originating in The Power of Shazam!, has the same powers from the same benefactors as her brother (Solomon, Hercules*, Atlas, Zeus, Achilles, and Mercury). A power-sharing element was added to the mythos in the Power of Shazam! series; one finite source of power was shared between Mary, Captain Marvel, and Captain Marvel Jr. It should be noted that this power-sharing element has not been honored by all later appearances of the Marvels. Mary loses these powers in the 2006 Brave New World one-shot special. In early stories, if she had lost her memory or been transformed, her transformation would restore her.

In Countdown to Final Crisis (2007–2008), Black Adam gives Mary his powers.[12] Since Adam was not sharing his powers with anyone else when he granted them to Mary,[13] and had also been carrying the powers of his dead wife Isis[14] (who had granted them to him with her death), Mary is now more powerful than she's ever been. Mary's patron deities become seven Egyptian gods: Shu, Heru, Amon, Zehuti, Aten, Mehen, and the "most powerful"[15] Egyptian deity, Isis, which increases her other powers and allows her to perform magical feats like weather control and transforming others. Mary's powers continue to expand rapidly as she and her mentor Eclipso seek new sources of magical power for her, gaining various new magical powers. She became sufficiently powerful to withstand Darkseid's Omega Beams. Eventually realizing she had been corrupted by Eclipso and the powers of Adam's gods, Mary relinquished these abilities. Mary's powers were restored when she aided the Olympian Gods in retaining their freedom from Apokolips. Later, her Black Adam powers were restored, given to her by Darkseid.

In the later Final Crisis miniseries (2008–2009), Mary's body was further enhanced with genetic technology stolen by the Atomic Knights. In addition to her impressive magical powers, her empowered form is now "aged" from late adolescence to adulthood, with clawed hands able to slice through metal. Later Black Adam restores her powers from the Egyptian gods. She is able to bestow part of it upon Billy, making him Black Billy.

Power of Shazam: Formerly, in order to change form, Mary had to call upon the name of Shazam, thereby invoking spells involving the energies of those extradimensional beings once known as gods on Earth. When Mary Batson said the magic word "Shazam!", she would be transformed into Mary Marvel. In her Mary Marvel form, Mary possessed the following attributes:

S

Wisdom of Solomon

As Mary Marvel, Mary had instant access to a vast amount of scholarly knowledge, exceptional photographic recall and mental acuity allowing her to read and decipher hieroglyphics, solve long mathematical equations instantaneously and make intuitive guesses based on limited data to the point her guesses were almost always correct. The wisdom of Solomon also gave Mary clairvoyance and provided her with counsel and advice in times of need. She had knowledge of all languages, ancient and modern, and could hypnotize people.

H

Strength of Hercules

Mary Marvel had incredible amounts of super strength, was strong enough to lift at least 100 tons, and was able to effortlessly bend steel, punch through walls, and lift massive objects. Mary's strength is enough that she has fought beings such as Captain Atom and Supergirl to a standstill. Her strength parallels that of Superman.

A

Stamina of Atlas

Using Atlas' endurance and durability, Mary Marvel could withstand and survive most types of extreme physical assaults. If she were somehow wounded, her godly energies would enable her to recover with superhuman speed and with more finality than mortals. It would take an injury of such magnitude that it dispersed a major portion of her bodily molecules to cause her a physical death. Even then, it might have been possible for a god of significant power, such as Zeus, Poseidon and Apollo, or for a number of Olympian gods of equal power working together, to revive her. Additionally, her Olympian metabolism ensured that she did not need to eat, sleep, or breathe when in Mary Marvel form.

Z

Power of Zeus

Zeus' power, besides fueling the magic thunderbolt that transformed Mary Marvel, also enhanced Marvel's other physical and mental abilities, provided physical invulnerability and resistance against most magic spells and attacks, and allowed her to access the Rock of Eternity. Marvel could use the lightning bolt as a weapon by dodging it and allowing it to strike an opponent or target. The magical lightning had many other uses, including creating apparati, restoring damage done to Marvel, or acting as fuel for magical spells.

A

Courage of Achilles

Like the wisdom, this aspect is primarily psychological and gave Marvel superhuman amounts of inner strength from which to draw. She was always supported by an innate and harmonious presence of good will and strength of perseverance so that she never backed down from a challenge.

M

Speed of Mercury

By channeling Mercury's speed, Mary Marvel, while not as fast as the Flash, could fly and move at hypersonic speeds exceeding Mach 10 (2 miles a second) while in Earth's atmosphere and could fly at close to light speed through space. She could move fast enough to not register in the normal peripheral range of humans and seemingly vanish and disappear at will. At this speed, her mind processed information on par to a computer or at least on a subliminal level that she was aware of her surroundings. She could also mystically fly through the atmosphere through sheer act of will, enabling her to soar through the atmosphere at sub-orbital levels and travel across the planet. She was immune from the effects of extreme height, such as dizziness and lightheadedness. With effort, she could travel from the earth to the moon, but required extra-precautionary paraphernalia for interstellar travel. Hermes Trismegistus (Greek for "thrice-great Hermes"), an occultist aspect of Hermes/Mercury, also gave her the ability to wield magic and cast spells, though she never used this as Mary Marvel, apparently because she did not know how.

In the final issue of 52, a new Multiverse is revealed consisting of 52 identical realities. Earth-5 is depicted as home to the Marvel family characters. As a result of Mister Mind "eating" aspects of this universe, it takes on aspects similar to the pre-Crisis Earth-S. Although the characters are not named in the panel in which they appear, a character looking like Mary Marvel is shown.[16]52 co-author Grant Morrison has made clear that this alternate universe is not the pre-Crisis Earth-S.[17]

An evil version of Mary Marvel exists in an alternate universe as a member of the "Power Posse" (evil analogues of the Super Buddies). Mistress Mary, as she is called, wears a black variant of Mary's traditional outfit, almost identical to her costume during the 2007/2008 Countdown series.[18]

In the 2007 limited series Shazam! The Monster Society of Evil, written and illustrated by Jeff Smith, Mary Batson is depicted as a prepubescent child who does not age when she transforms into Mary Marvel.

Mary meets her lost brother in the circus that is attacked by Alligator Men and is rescued by Captain Marvel. With the help of Talky Tawny, a trickster spirit who changes into various forms but prefers being a tiger when convenient, the siblings learn they are related. When Billy transforms into Captain Marvel, Mary stands too close to her brother and is struck by the fringe of the magic lightning. As a result, Mary gains her Marvel form (which is still at her actual age) that is apparently based on the aspects of various goddesses, including superior flying speed to her brother, and powers stemming by a female set of benefactors. For example, Athena's wisdom is different from Solomon's, allowing Mary to perceive "life vibrations" and distinguish between living and non-living beings.

Although she and Billy are kidnapped in their regular form by Doctor Sivana and Mr. Mind and gagged, Billy escapes and rescues her as Captain Marvel when she is thrown from the top of a robot by Doctor Sivana and removes a piece of duct tape from her mouth, allowing her to transform. When Billy accidentally loses his Marvel powers due to a wormhole drawing them away, Mary restores them to him by calling down the lightning and touching him as it strikes.

Mary appears as a main character in this follow-up series. As in Monster Society of Evil, Mary has only a fraction of her brother's powers and remains a child in super form. Although faster, she is far less strong. As such, her brother is very protective of her, even in her Marvel form, although her great courage and cunning are undisputed. She is also more hyper as Mary Marvel.

In the digital Justice League Beyond comics taking place in the DC Animated Universe's future (based on the Batman Beyond tv series), Mary Marvel, Billy Batson, the wizard Shazam, and Black Adam are somehow sharing the same body. Only one of them can exist in the real world at a time, but can switch places with each other. She appears to be attracted to the Green Lantern of that time period. It is unknown how this occurred.

Mary Marvel (as Mary Batson) appears in the Batman: The Brave and the Bold episode "The Power of Shazam!" voiced by Tara Strong. As with the origin of her appearance, both Mary and Billy are reunited at the end of the episode when they discover a locket that helps them reconect as brother and sister after Batman did some detective work that found her. She returns in "The Malicious Mr. Mind!", this time with the ability to transform into Mary Marvel. She and the other members of the Marvel Family, along with Batman, battle Mister Mind and the Monster Society of Evil.

Greg Weisman (producer of the TV series Young Justice) has confirmed that Mary Bromfield was a member of the Team in between seasons 1 and 2 and was known as Sergeant Marvel. Mary was supposed to appear both in and out of costume at Rocket's bridal shower in the episode “Satisfaction” but was cut from the finalized episode.[19][20]

Although she has not appeared in any other television programs or films, Mary Marvel is featured in issue 20 of the Justice League Unlimited comic book, in which she appears in the art style of the Justice League Unlimited television show.

She made a cameo appearance in Teen Titans Go! as a member of the Justice League in Beast Boy's fantasy.
